Installing a new gear without replacing all the grease is the single biggest mistake DIYers make — it causes the new gear to fail within months. Use food-grade, heat-resistant mixer grease only. KitchenAid-branded grease or any food-safe high-speed gear grease works. Budget 4–6 oz and do it right the first time.\n\u003c\/div\u003e","brand":"XPart Supply Ltd.","offers":[{"title":"OEM","offer_id":52782891041057,"sku":"WP9709231","price":44.35,"currency_code":"CAD","in_stock":true},{"title":"Used","offer_id":52782891073825,"sku":"WP9709231","price":19.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/7783\/2225\/files\/KitchenAid_Stand_Mixer_Worm_Gear_WP9709231.png?v=1780182414","url":"https:\/\/xpartsupply.com\/products\/wp9709231-kitchenaid-stand-mixer-worm-gear","provider":"XPart Supply Ltd.","version":"1.0","type":"link"}
